WASHINGTON (AP) Matt Adams is returning to a Nationals team he believes is better than the one he was traded from and has the potential to make even more moves this offseason.

Adams finalized a $4 million, one-year deal on Tuesday that includes a $3 million salary for next season and a $4 million mutual option for 2020 with a $1 million buyout. The 30-year-old first baseman is back with Washington after being traded to St. Louis in August for $50,000.

The move by general manager Mike Rizzo fills a void with a left-handed hitter who's expected to split time at first base with Ryan Zimmerman.
